ARM Architecture Reference Manual
The purpose of this manual is to describe the ARM instruction set architecture, including its high code
density Thumb® subset, and three of its standard coprocessor extensions:
• The standard System Control coprocessor (coprocessor 15), which is used to control memory system
components such as caches, write buffers, Memory Management Units, and Protection Units.
• The Vector Floating-point (VFP) architecture, which uses coprocessors 10 and 11 to supply a
high-performance floating-point instruction set.
• The debug architecture interface (coprocessor 14), formally added to the architecture in ARM v6 to
provide software access to debug features in ARM cores, (for example, breakpoint and watchpoint
control).-ARM Architecture Reference Manual
